Entertainment Weekly has learned that the mother of Laurel Lance will be played by British actress Alex Kingston. The "ER" and "Doctor Who" alum will reportedly return to Starling City in an attempt to win back the family she left after her daughter Sara.

Like everyone in the "Arrow" universe, we'd bet that Dinah is more than meets the eye. Is her real motive just to make amends with her ex-husband Detective Quentin (Paul Blackthorne) and her daughter (Katie Cassidy)? Or does she have some ulterior reasons for her return? Honestly, it would be as much fun if Dinah didn't have a couple tricks up her sleeve.

At least Kingston knows a thing or two about nerd culture thanks to her role in "Doctor Who." Hopefully she'll make as big of an impact in "Arrow" as she did in the BBC series as River Song.
